Supporting structure for steel dam door

The invention relates to the technical field of steel dam door supporting, in particular to a supporting structure for a steel dam door, which is characterized in that the dam door is fixed on a base station through a dam door supporting seat, a plurality of upper supporting arms are arranged on the rear end face of a dam door body, the upper supporting arms are in shaft connection with lower supporting arms through supporting mechanisms, and the lower supporting arms are in shaft connection and fixed on a lower supporting seat; an arc-shaped sliding groove is formed in the supporting mechanism, a steel ball is arranged in the arc-shaped sliding groove in a matched mode, and the steel ball slides in the arc-shaped sliding groove. The supporting structure adopts a pure mechanical structure, so that the supporting stability and safety of the steel dam door are enhanced, the fault rate of the supporting structure of the steel dam door is reduced, and the user cost is reduced. 本发明涉及钢坝门支撑技术领域，尤其是涉及一种用于钢坝门的支撑结构，包括坝
